prepare to answer alot of questions about eachother-so practise! fav colors,foods,tv shows,about eachothers families,dreams and plans you have together,which side of the bed eachother likes,fav hobbies.......... so on-they want to see if it is a genuine relationship and you should know alot about eachother. The only answers they have is on the papers you have given them already-and they will likely check the answers,the rest you can bs if you don't know the answer...just don't say"i don't know-make the best guess you can but PREPARE! they may ask about your relationship as well as some very personal questions so don't be shocked. Good luck
